Specification of Letters Patent.

Application filed December 19, 1914. Serial 110.8783.

To all whom it may concern:

Be it known that I, HENRY Kmosrono HARRIS, a subject of the Kin of England, residing at 96 Victoria street, ndon, England, haveiinvented certain new and useful Improvements in and Relating to Advertisin Devices; and I do hereby declare the fo lowing tobe a full, clear,and exact description of the'invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to devices for making public announcements, exhibiting advertisements and for other purposes of a like nature, and refers to improvements upon that type of such devices in which selectormechanisms are provided which mechanisms control the movement .of the exhibiting means and select the indications which are to be exhibited, the band or other equivalent means such as cards, plates, disks or the like can ing the indications being wound or move backward or forward, the operation being controlled from a distant station preferably in conjunction with the control of the exhibiting units.

According to my present invention I provide a selector which not only determines the indication which is to be set but which also determines automatically on the transmission to it of the required number of impulses to select the indication) the direction in which the band or its equivalent on the particular unit shall wind or be moved, the construction being preferably such that it is only requisite to wind or move through the number of steps which make up the dif- {erenee between" the fresh setting and the ast.

In one form of carrying out the invention, the selector may comprise a wheel or other moving part, which is operated to determine the fresh indication it is desired to exhibit, and a counting wheel or other device which is set in position by the last setting. Each of these wheels or the like carries a stop which preferably may take the form of' an electric contact but which might be mechanicalfi In'one form the selector 'wheel makes one or more contacts during itssettirrg which determine the direc tioir of subsequent winding of the unit, and these contacts are made according to the movement of the setting wheel or the like in'relation to that wheel or the like which has been set by the last indication. Further when the'contaots on the two wheels or the like meet on the windin of the unit the movement is stopped at t e desired indication, the selector wheel is then turned to zero which may be effected by a spring wound by its previous movement ready for the next setting. The above devices mav be used for the control of units driven by t eir own'individual motors, or for the control of those driven collectively, with any form of gearing. The object of the invention is to bring the band or like device into position with the least possible displacement and preferably without its being necessary for the operator to have to take into con sideration the previous setting. In one form when the units are driven by their own individual motors, the transmission to the drums may be byv worm drive, but I may use any kind of driving mechanism or gearing, in some cases a differential gear, the wheels of which may be locked or released to bring about the required movements. The counting Wheel that runs in synchronism with the band may in some cases be used to limit its motion in either direction.

The selector mechanism may be placed on an inclosed plate at the top of the machine and so constructed that it is readily accessible and easily removable without disturbing the rest of the unit, so that it can be replaced. The diflerent units may be switched into circuit by a unit selector which in one form may be returned to zero by its spring when a circuit is closed on the completion of the setting of all the units, or it may be driven by its own motor. 7 And in order that my said invention may be better (understood, I will now proceed to describe the same with reference to the drawings accompanying this specification in which Figure 1 shows a side elevation of an advertising unit constituting a portion of my invention;

Fig. 2 shows a sectional rear elevation of a portion of Fig. 1; V Fig. 3 shows in side elevation and Fig. 4 in plan a selector mechanism for use with an advertising unit sueh as that shown at Figs. 1 and 2;

i The same letters and numerals denote the same parts iii ail the views.

Referring to Figs. 1 to 7, 11 is the band carryin the letters, numerals or other devices. he band 11 is rolled between drums 12 and 13, the drum 13 being driven by a motor 14 at the required times. The motor imparts its movement to the drum 13 by a pinion 15 on the motor shaftrunning in gear with a wheel 16 the wheels lfi and 16 being located in an oil bath 17. {On the spindle of the wheel 16 outside the casing is mounted a friction wheel 18 which runs in frictional contact with the interiorrof the drum 13. The motor 14 can be driven in either direction according to the direction of the currentsupplied thereto and thus causes the drum 13 and consequently the band 11 to be moved in either direction. The dru1n 1-3 is mounted by means of ball bearings 19 on a 'fixecl hollow axle 20 provided with a lining 21 of insulating material the hollow insulated interior of this axle forming a conduit for the electric conductors. The drum .12 is mounted so as to turn about a fixed axle 22 and has attached thereto so as to rotate therewith a pinion 23 gearing with a. wheel 24 attached to a spring barrel 25 rotating upon a fixed axle 26 fastened tozthe framework 27 which also carries the fixed axles ofthe drums 12 and 13. 28 is a spring in the interior of the spring barrel 25 one end of which is attached to the fixed axle 26 and the other end to the interior of the barrel 25.

When the motor 14 is turned in such a direetionasto cause the band 11 to move downward it will be seen that the spring 28 is wound up and consequently when the motor turns in the opposite direction the spring 28 in unwinding winds the band 11 back on to the drum 12,

It will be understood however that the drums 12 and 13 can be geared together in any suitable way to effect the desired operation.

*At Fig. 7 is shown another method of imparting rotation to the drum 13 from the motor 14. In this case the axle of the motor is furnished with aworm 29 gearing with a worm wheel 30 the shaft of which carries the friction. wheel-18.

With this form of device any tendency the spring may have to cause the band 11 to move upward when not required 1s prevented.

The direction in which the motor 14 is caused "to run is controlled by the selector mechanism about to be described, more particularly with respect to Figs. 3 and 4. 31 is a toothed wheel forming the selector Wheel mounted upon an axle 32, so that it can turn in either direction. 33 is a polarizedmagnet, the armature '34 of which is caused to move either up or down (with reference to Fig. 4) according to the direction of the cilrrent sent to the magnet. 35 and 36 are .two independent pawls pivoted to the end of the armature 34 and kept pressed against the teeth of the wheel 31 by flat springs '37 and 38 carried by the armature 34. 39 are helical springs for keeping the armature 34 normally midway between the poles of the magnet 33. In place of springs 39 the ends of the armature maybe located between two spring bufiers 39 which hold it normally in the central position, as shown in Fig. 19. 40 and 41 are fixed stops against which the pawls 35 and 36 take. When a current of one polarity is sent to the magnet 33 it causes the armature 34 to be moved in one direction say for example (with reference to Fig. 4) in the upward direction. This action causes the pawl 36 to press against the pin 41 which thus forces the pawl 36 out of contact with the wheel 31, at the same time the pawl 35 being freed somewhat from the re- 100 straint of the pin 40 is forced into the teeth of the wheel 31 by the spring 37 and consequentlythe movement of the armature 34 causesthe pawl 35 to move the wheel 31 through the distance of one tooth in the di- 105 rection of the arrow 42. When the circuit is broken through the magnet 33 the parts return to the position shown at Fig. 4 the Wheel 31 being prevented from turning back by the friction brake, 43.

It will, therefore be understood that the wheel 31 is turned through the same number of teeth in any desired direction as the num= ber of electric impulses of one polarity sent to the magnet 33, and the position taken 115 III) by the wheel determines the direction in which the motor 14 is subsequently caused to run, as well as the time for which the motor runs, in the manner now to be described. 120

Fixed to the wheel 31 and beneath the same is a'wheel 44 provided with a flange 45, which flange'45 has a portion 46 cut away, the walls of the cut away portion being sloped as shown at Fig. 3. 47 is an insu- 125 lated projecting pin normally projecting into and being easily accommodated by the cut away portion 46. 48, 49, 50 and 51 are electric contacts, the contacts 48 and 49 coming on a higher level than the contacts 50 130 I by the p 41hr tioh of the motor w ser? and 51, as .shownat. iEigrit 2 18 1 1. 53 a two me aliiespringyanns, insulat dsfm caoho h ls andeoonncctedat theicfree d to insuiated pin. 4:7, The spring ar s 52 k and 5,3 are adapted to take up oneof three poarm 2 to make electrical connection between the contacts 48 and 41,9, and it may be here remarked that these contacts are so connected to the electrical circuit oftheapparatus that at. the required time, when other contacts have been made, the motor '14: is

V caused to run in one direction. If, however,

the pin 47 be caused to ride "down the other sloping wall of the .cut away'portion 46 bythe reverse settingeof theselectorit causes the arm53 to make electrical connection-between the contacts and 51, which are so connected to the electrical circuit that the motor 14 is subsequently caused to rotateinga direction opposlte to that previously described.

Referring now to the parts already described with reference to the diagram, Fig. 6, the magnet 33 is operated by impulses sent in either direction on the lines 54 and 1 1:5, The particular unit in circuit is of course chosen the commutator switch 56 operated in any, desired manner. .It will be seen that the circuit is completed between the brushes 57 and 58 and the contact plate 59, the two former being mounted upon the frame 27 of the unit and insulated therefrom, the latter being carried by the drum 13 (see-Fig. 1).

In Fig. 6 the reversingswitch controlled reversing em er, ds: scribed with refer nce t increases to 51 is designated by the reference numeral 60 7 When all the selectors have been set, cur rent is sent to; the linesfil and 5 5. This causes 'a motor starter 62 to bring the contacts 63 and 64 together thus throwing the motor 14:. into circuit of the local power 65. The'motor commences to rotate, the direction being controlled by the position of the selector. wheel 31 that is it depends upon whetherzthe said wheel hashbeenmoved in sucha dircctionras to cause the pin 47 to oomelahove or below the flangeb, i

QReferring now to the mechanism shown at Fig; 5, Q6 is a shaft, which is either a por- 7 shaft or a shaft suitably geared :thereto. :This shaft ,has loosely niounted' thereon a sleeve 67, provided with an inclined slot 68 into which projects a pin 7 this?! iasaaci cre ela ifoun di n e, w h he e e '67-. It Will i n i rst d. that hen the shaf hfifi i dri ven in the, directionofthoarrow 71 the pin 69 will cause the sleeve 671:0 move to the left and to occupy the position in which it is shown at Fig. 5, while when the shaft rotates in the opposite direction, the sleeve is moved to the right. The movement of the sleeve controls the operation of a reversing switch 72, which is so connected to the circuit that when current of one polarity has been sent to the magnet 33, upon the subsequent starting of the motor the sleeve 67 is so movedas to cause the switch 72 to take up such a position that current flows from the local source through the magnet 33 in the opposite direction to that of the impulses which set the wheel 31.

The circuit for this connection is as follows Starting from the negative side of the source of power 65, the circuit can be followed to one arm of the switch 72. It passes thence to thel ine 55,then through the polarized magnet 33120 the brush 57, through the cont-act 59 to the brush 58. back to the other arm of the switch 72 and thence back to the source of power. It will be understood that as the drum 13 rotates, this circuit is broken every time a plate 59 leaves the brushes 57 and 58, so that in this way a series of impulses is sent to the polarized magnet of opposite polarity to those previously sent, causing the wheel 31 to be set back step by step, until the cut away portion 46 allows the pin 47 to spring into it. This breaks the circuit of the motor, which consequently stops.

At Figs. 1 and 6, it will be seen that two plates 59 are provided 80 apart. This is necessitated by the fact that the indications on the band 11 are two to a single revolution of' the drum 13; The band 11 has,

therefore, been moved through a; number of indications corresponding to the number of impulses sent to the selector wheel 31. When the motor stops, the shaft 66 ceases to rotate, and the governor 7 3 mounted thereon causes the movable plate 7 4 in connection therewith to move toward the right. This allows the spring arm 75 to break contact with the screw 76, thus breaking the circuit of the reversing switch 72 across the lines 54 and 55. This is necessary to pre venta shunt across the said lines when fresh impulses are sent from the transmitting sta tion to the polarized magnet 33.

Although the selector has been shown ac tuated by a 'polarized magnet, it is obvious that I may use two ordinary magnets for controlling the selector and separate contacts for each on the drum. which only make contact 7 in one direction. Either magnet would be operated according to the direction in which the drum traveled; x

&

Referring now to Figs. 8 and 9, which illustrate another form of selectin mechanism, the great advantage of this orm lies in the fact that a standard number of imulses have always to be sent to the exhibitmg station for any particular indication, so that the operator where hand setting is employed does not have to take into consideration the previous setting. 3

In the drawing, a shows the selector wheel, the magnet for operating which is not shown, but which always sets it in a counterclockwise direction against the action of a spring contained in a spring barrel at the base of a wheel in connection with a flange d, siinilar in all respects to the wheel 4i and the flange 45. This wheel is carried by the selector wheel a, and moves freely around a pivot projecting from a counting wheel g. p is a magnet carried by the counting wheel 9, and g 1s a spring catch normally engaging with the teeth of the selector wheel a, without however preventing it being moved by its actuating magnet. The catch 9 is pivoted in guide brackets carried by the wheel 9.

When the magnet 19 is energized, the stem r forces the catch 9' out of engagement with the wheel a and allows the said Wheel to spring back until the projecting pin or roller 6 comes into contact with a stop a constitilted by one arm of a lever s pivoted upon a pin attached to the wheel g. The other arm of the lever s is provided with a hook at t and is kept pressed downward by a ipring u, so that when the catch 9 is forced rom engageinent with the teeth of the wheel a, the hook 1! takes behind the nose to on the catch 9, thus holding the said catch out of engagement with the wheel a, until the projection b comes around in a clockwise direction, into forcible contact with the stop 0,. knocking the hook t out of engagement and allowing the catch 9 to again swing inward. w is a pin for limiting the movement of the stop 0. e indicates the neutral position on the flange d. I

It should here be observed that when the selector wheel a is set forward, that is, moved in a, counterclockwise direction, by its electromagnet receiving a certain number of electrical impulses, the said wheel alone rotates, the wheel 9 being preventedfrom rotating by means of a spring pressed detent c or by its engagement with the gear wheel 2. The wheel 9 is only moved in either direction by means of the gear a rotating synchronism with the drum 13, but at the same 7 time when the wheel 9 rotates ii either direction, it carries around with it the selector wheel a and flange d which may be described as a double cam. The selector wheel is allowed to move, since its actuating pawl when not Iworking is out of engagement with the teet The action of this form of the selector will now be, described with reference to the diagaammatic representations thereof shown at gs. 10 to 17 which show the form of selector described in detail with reference to Figs. 8 and 9, in difierent positions.

In these figures, a shows the selector wheel, 6 a pin projecting therefrom, d a double faced cam controlling, by the direction ofj jts rotation, the position of the switch arm 7. a indicates the neutral position. The cam d is attached to the selector wheel a and moves therewith. 9 shows the counting wheel, which is moved through one step every time the band in the particular unit to which it is connected moves through the distance between one indication and the next consecutive one. The wheel 9 carries a stop 0 against which the projection b is adapted to tal fe. k is an arrow which indicates on the counting Wheel 9 the particular indication being shown in the exhibiting unit. it is the zero position. 7

It will be understood that the selector wheel a is setforward, that is, it is moved in a counter clockwise direction by a suit able el ctroinagnet through a number of steps corresponding to the number of impulses sent to the particular unit to which it is connected.

The position of the parts in the zero position, that is in the position in which no indication is being exhibited, is shown in Fig. 10, where it will be seen that the projection b is in contact with the stop a and the switch arm f at the zero position of the cam d. In this position, the motor to which the switch controlled by the arm f is connected, similar to that shown at Figs. 1 and 2, is out of circuit. The arrow 7:: also indicates zero on the wheel 9. V

Supposing it is desired to set in the unit the indication corresponding to five impulses, these impulses are sent to the electromagnet controlling the selector wheel a, which is moved into the position shown at Fig. 11; it also causes the cam d to move through five units of distance, removing the neutral position 6 a similar distance from the arm f, which aim is consequently forced to the under side of the cam d and this sets the motor driving the unit, so that when the motor is subsequently started the band roller causes the countin wheel 9 to move in the direction of t e arrow m through the gear a (Fig. 9). It will also be observed that the pin 6 has :moved through fiveunits of distance from the stop a, it being reinembered that the wheel g is only moved y the moving part carrying th indication such for example as the band drum, an not by the selector, and, therefore. remains at rest. 7

the i i grmot r s a e the some wfieei y, the selector a and the cam iio ' e are' mrneil back as a whole, that is moved in a "clocliwise direction! When five 7 units of distance have been turned back. the neutral position 6 comes opposite the arm 1 which consequently breaks the circuit of the driving motor, which then stops, the parts remaining in the position shown at Fig. 12. It w1ll be seen from this figure that the arrow It indicates the fifth posi- 10 tion and therefore the fifth, or in other words the desired indication is" being ex- ;hibited"in tlre unitj V p I I Befor sendin' impulses to 'the unit the sele' s1 owed to spring back bringmg the'pin'b iifcontact with the stop 0 (in the manner previously explained). This brings the position of the parts to that shownin Fig. 13. "The neutral position e is displaced five units of distancein Fig. 13, but this does not cause the motor to start owing "to the fact that the circuit is broken in other positions, as will be readily understood.

Now when it'i's desired to set the band into a fresh osition it is not 131-5 1: *set it to zero and then forward to the new position butit is only necessary to move the hand through the difl'erence in the two settings. 7

This is done in-the following way-:&

Taking the first case in which the' number of impulses of the second setting is greater than those of the first setting, say for example in thejcase under consideration ei lit impulsesrare to besentz' iThe selector 1 'eli d set forward (counterclockwisefby these impulses'and take up "the ositionshown; at Fig. 14, the neutral ion e three units of distance to the other side-o thearm fand the pin b V 40' 'eightfunits ofdistance ffrom the stop a. the motor isstartedby' the other necessitry contacts being made at the required time, the wheel g,selector wheel a and cam 03 are moved in the direction offtlfearrow 'm distance has'fltakeii piace,

When the driving motor is started it will run in the opposlte direction to that in the case previously under consideration, asit will be seen that the arm f is on the opposite side, that is the upper side of the cam 03 to that, say for example shown atFig. 1-1,'this as previously explained reverses some of the windings of the motor, throu h the reversing switch and consequently w en the motor is started'efl'ects the reverse drive. The countin wheel g, selecting wheel a and the cam d therefore rotate in the direction of the arrow a (reverse to arrow me) until af ter moving through three units of distance the neutral position 6 comes opposite the arm f and stops the motor. The parts are now in the position shown in Fig. 17 Where the arrow It indicates two, showing that the band is exhibiting lthe second indication. The pin 6 is also two divisions from the stop a and is causect;at the desired time, to spring into contact with the stop. 7

It should be observed from the diagrams (Figs. 12, 15, 17 that when the band is exhibiting the required indication or the like the in b occupies the in ig. 10 and alsoin t ese figures (12-, 15 and=17)"the pin b is the same number of divisions from tliestop c; as thenumber of imulses sent and consequently when the pin springs to'the stop cgthe neutral position eis the same number of divisions or units of distance from the arm'fas impulses sent, "*see Figr13. It will also be understood that the next '"osition after Figs. 15 and 17 will also fulfiFthis condition.

The core 84jof. the solenoid 80'is connected to the arm 82 and consequently when the saidsolenoid is energized the arm is ullgidover a? the ieft (which is shown in FigQlSin full-dines in the'interniediate position). "In the extreme position to the left it connects the twnlcentacts 85 and 86 which bring'the windings of the motors 14 into the supply circuit. 7 The motors rotate in the direction according to where the switch rm f has been located; the action of the said switch in this case rovers ing the flow through the armature windings. The movement of the band in a particular vertising member, a selector wheel for controlling said movable member, a counting Wheel upon which the selector wheel is loosely mounted, an operatin magnet, means whereby the selector whee can move forward under impulses sent thereto without moving the counting wheel, and means moving in synchronism with the movable member for moving the selector wheel backward by the counting wheel when the same is rotated.
